Abstract
A method for transmitting data in a transmitting device of a wireless network comprises transmitting one or more data packets to a receiving device via a reserved region comprising channel resources allocated by a coordinator, and transmitting channel time extension information for requesting channel time extension to the receiving device, in order to transmit the data packets on an unreserved region in which the coordinator does not allocate channel resources to any devices.
Claims12
A method for receiving data by a receiving device in a wireless network which comprises at least a transmitting device, the receiving device, and a coordinator, the method comprising:
- receiving a plurality of data packets from the transmitting device during a reserved channel time allocated by the coordinator, each of the plurality of data packets comprising a header which includes a channel time extension (CTE) field, wherein the CTE field of a last data packet among the plurality of data packets is set to a value to inform the receiving device whether or not the transmitting device will continue transmission to the receiving device during an unreserved channel time, and wherein the CTE fields of the plurality of data packets other than the last packet among the plurality of data packets are set to a first value;
- and
- receiving a data packet from the transmitting device during the unreserved channel time if the CTE field of the last data packet is set to a second value.
An apparatus for receiving data in a wireless network, the apparatus comprising:
- a receiver;
- and
- a controller cooperating with the receiver, wherein the receiver is configured to:
- receive a plurality of data packets from a transmitting device during a reserved channel time allocated by a coordinator, each of the plurality of data packets comprising a header which includes a channel time extension (CTE) field, wherein the CTE field of a last data packet among the plurality of data packets is set to a value to inform the apparatus whether or not the transmitting device will continue transmission to the apparatus during an unreserved channel time, and wherein the CTE fields of the plurality of data packets other than the last packet among the plurality of data packets are set to a first value;
- and
- receive a data packet from the transmitting device during the unreserved channel time if the CTE field of the last data packet is set to a second value.
